Antibodies are essential components of the immune system, identifying and neutralizing foreign invaders such as bacteria and viruses. In research and therapeutic applications, obtaining antibodies in their purest form is crucial for ensuring accurate results and effective treatments. This process, known as antibody purification, involves isolating antibodies from complex biological mixtures to achieve high purity and specificity.
Why Is Antibody Purification Important?
In both research and clinical settings, impurities in antibody preparations can lead to inconsistent results, reduced efficacy, and potential adverse reactions. Purified antibodies provide reliability and reproducibility in experiments, diagnostics, and therapeutic interventions.
Methods of Antibody Purification
Several techniques are employed to purify antibodies, each tailored to specific requirements:
1. Protein A or G Purification
Protein A and Protein G are bacterial proteins that bind selectively to mammalian immunoglobulin G (IgG) antibodies. This method isolates total IgG from sources like serum, ascites fluid, or cell culture media. The choice between Protein A and Protein G depends on the species and subclass of the antibody. However, this technique is not recommended for peptide antigens, as antibodies against larger carrier proteins may also be isolated. It is best suited for antiserum produced using protein antigens and for purifying monoclonal antibodies from ascites or cell culture media.
2. Immuno-Affinity Purification
This method isolates antigen-specific antibodies by coupling an antigen to a gel matrix, creating a column that captures the desired antibodies. It is particularly effective for isolating peptide specific or protein antigens and for purifying monoclonal antibodies. Here at Pro Sci We use both peptide or protein antigens for Immuno-Affinity Purification.
3. IgY Purification
Chicken IgY, functionally equivalent to mammalian IgG, is primarily isolated from egg yolks. The purification process involves removing lipids and precipitating antibodies from the resulting solution. The total IgY can be used directly or further purified using an immuno-affinity column.
